Well it is a matter of your own opinion but for my part I will never again mount anything on the back of a 5th wheel. Long story short it was not properly welded and we almost had a horrible accident during rush hour traffic while going through Atlanta. A lot of people do this without problems but for me never again! A 5th wheel has a lot more bounch in the back than a TT so if you decide to do this make sure it is done by a professional and is done well. Good Luck.
